We compare the numerical methods that are most widely applied in the computation of the standard business cycle model with flexible labor. The numerical techniques imply economically insignificant differences with regard to business cycle summary statistics except for the volatility of...

On the one hand, recently a number of theoretical models have highlighted the role of credit market frictions in propagating and amplifying macroeconomic shocks. On the other hand, it still seems an open question whether this role is quantitatively significant. Our paper tries to fill this gap....

By simplifying the computational tasks and by providing step-by-step explanations of the procedures required to study a linear dynamic rational expectations (LDRE) model, this paper and the accompanying “LDRE Toolbox” of Matlab functions guide a researcher with almost no experience in...

Lucas [1987] has shown that in a representative agent framework, the potential welfare gain from stabilizing consumption around its mean is small. We provide an example and some insight for why Lucas’ measure is an upper bound of the welfare cost of fluctuations in walrasian economies.

Capital adequacy regulations specify a minimum capital-to-assets ratio for banks in the economy. The effects of these regulations on the level of economic activity have not been thoroughly studied by the banking regulation literature. Specifically, the fact that as proposed by the Basle Accords,...

Value function iteration is one of the standard tools for the solution of the Ramsey model. We compare six different ways of value function iteration with regard to speed and precision. We find that value function iteration with cubic spline interpolation between grid points dominates the other...

This paper compares different solution methods for computing the equilibrium of dynamic stochastic general equilibrium (DSGE) models with recursive preferences such as those in Epstein and Zin (1989 and 1991) and stochastic volatility. Models with these two features have recently become popular,...

This paper develops a dynamic general equilibrium model with heterogeneous firms that face search complementarities in the formation of vendor contracts. Search complementarities amplify small differences in productivity among firms. Market concentration fosters monopsony power in the labor...

Spanish Abstract: Teniendo como marco de referencia la “estrategia de inflación objetivo” es usual discutir lo que es m ́as conveniente para una sociedad en cuanto al grado de “dureza” o “agresividad” de una autoridad monetaria para defender su meta de inflación, y la credibilidad...
